Or perhaps humans are lazy by nature and, since PHP does a very bad job of keeping us in line, the less disciplined of us end up writing bad PHP code. Of course, if we don't know how to write good code to start with, it's not PHP's fault. I think the simple fact that you can write good, elegant PHP code goes to show that it simply demands a more disciplined programmer (or a framework to help with that discipline).
